IMPROVEMENT-IN GRAIN-DRILLS.

Specification forming part of Letters Patent No. 144,452, dated November 11, 1873; application filed June 21, 1873.

To all whom may it concer: Be it known that I, SAMjUEL HART, of Fulton, in the county of Oswego and State of New York, have invented a new and Improved tional elevation of it taken on the line .r w of Fig. 1. Fig. 3 is a detail section taken on the line z z of Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents a long grain-hopper, extending across the front portion of the machine, with a chamber, l5, into which the grain escapes `through the passage, which is regulated by a gate, l). The side E of this chamber is made to lit nearly half around a small droppingroller, F, containing pockets G, opposite which there are slots H in the side E, through which the grain passes into the pockets. The roller has as many pockets as there are to be drills in the machine, and each pocket discharges into a spout, I, for sowing in drills. The roller is operated by the train of friction-Wheels J, K, and L, and the gears M and N, which are turned by the truck-wheel O. The wheel K is on rod P, which swings up and down to throw the dropper-roller out of gear while turning at the sides of the lield, and connecting it again. It is held in gear by the levers Q and R. y

To vary the feed to sow more or less grain to a given breadth, the opening O is varied by the gate D, and, in case it is required to make gether, and put them in. These drill-stocks carry the usual drill-opening tubes X, covering-scrapers Y, and pressing-rollers Z, and they are connected to a rod, a, by cords, `to raise them up out'bf the ground. The drops ping-spouts terminate over the drill-tubes, and have, when the machine is to be used for planting, a gate or valve, b, closing against the lower end by a spring-shank, to retain the grain until it should fall into the hill.` They are opened by arms d on a rock-shaft, e, which is turned at the proper time by the tappet-wheel f, lever g, and arm IL. The tappetwheel hasthree tap.- pets, and opens the valves three times to the revolution of the truck-wlicels but others with two tappet-s may be employed, if it be desirable to plant the hills farther apart.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of hopper A, provided with rotary feed-tube F, subjacent receptacles I, having trough closed by an `automaticallyopened valve, b, and the hollow opening plow X, arranged substantially as and for the pur- Witnesses: SAMUEL HART.
